The first wintry event of the season spread a mixture of snow and freezing rain across Eastern Pennsylvania during the morning of the 4th. Accumulations averaged 1 to 3 inches with some higher amounts in the Poconos. Except for parts of the Poconos, the snow changed to freezing rain before ending during the middle of the morning with ice accretions of one to two tenths in most areas. While this event occurred on a Sunday morning and cut down on traffic, because it was the first widespread wintry precipitation event of the season, numerous accidents, some with serious injuries occurred. Snow began falling shortly after Midnight EST on the 1st. The snow changed to freezing rain from around 5 a.m. EST in the Philadelphia Metropolitan area to around 7 a.m. in the Lehigh Valley. Precipitation ended between 9 a.m. and 10 a.m. EST.In the greater Philadelphia Metropolitan area in Bucks County a head-on two car crash on Pennsylvania State Route 309 caused a woman and child in both vehicles to be injured. In Montgomery County, an eight vehicle accident occurred on the Danenhauer Bridge in Norristown and closed the bridge for one hour. In Worcester Township, a man was seriously injured in a head-on collision. A number of serious accidents occurred on U.S. Route 422 including roll-overs and a vehicle that hit an embankment twice. All the major roadways around Philadelphia (the Blue Route, Interstate 95 and the Schuylkill Expressway) had accidents occurred. In Berks County, the eastbound lanes of Interstate 78 was closed in Tilden Township after a tractor-trailer jackknifed. In Douglass Township, Farmington Avenue was closed for several hours after a car driven by a 32-year-old male struck a small office building. In Northampton County, the westbound lanes of Interstate 78 was closed for one hour in Williams Township after a vehicle struck a disabled vehicle. In Forks Township, a vehicle drove into a home on Uhler Road. One lane of U.S. Route 22 was closed in Palmer Township because vehicles were sliding off the roadway. Several roads were closed because of icy conditions in Lehigh County. In the Poconos, several accidents occurred along U.S. Route 209 in Carbon County and about half a dozen accidents occurred along Interstates 80 and 380 in Monroe County.Accumulations included 4.1 inches in Lehighton (Carbon County), 3.8 inches in Saylorsburg (Monroe County), 3.3 inches in Springtown (Bucks County), 2.8 inches in Warrington and Sellersville (Bucks County), 2.5 inches in Boyertown and Hamburg (Berks County), Macungie (Lehigh County), Palm (Montgomery County) and Forks Township (Northampton County), 2.2 inches at the Lehigh Valley International Airport, 1.5 inches in Reading (Berks County) and Phoenixville (Chester County), 1.0 inch in Valley Forge (Chester County) and 0.6 inches at the Philadelphia International Airport. The greatest ice accretions (closer to two-tenths of an inch) occurred in the local Philadelphia area where the changeover occurred sooner. The wintry mix of precipitation was caused by a fast moving low pressure system that moved from Oklahoma on the morning of the 3rd to the Maryland panhandle at 7 a.m. EST on the morning of the 4th and was quickly offshore by that afternoon.
